E112 Explosion proof

The E112 is a popular model in our range of explosion proof flow rate indicators / transmitters. In addition to the average K-Factor, 15 linearization points can be entered. The unit will interpolate between these points greatly enhancing accuracy in any flow range. The E-series is distinguished by its high-quality manufacturing and its functionality driven European design. We believe, it is not just about fulfilling the requirements for explosion proof, but it is about safety during daily operation.
